Description
Resolution:
This can be achieved by using the query engine as a pre-filter and implemented as described below in the Query and Inference agents.
In the query engine:
1.) Listen to your external events in a destination D1.
2). Upon reception of an event in D1:
- Run the complex query.
- If the query finds an existing concept, do nothing.
- Else send the original event to the inference engine using a destination D2.
In the inference engine:
1). Listen to the events coming from the query engine through the destination D2.
2). Upon reception of an event in D2, always create the concept.
